Generally Thais are quite open to western ideas and behaviour but within certain limits. One should realise the King of Thailand is absolutely respected by Thai people and the monarchy should in no way be questioned or criticised. The majority of Thais (96%) are Buddhist and there are thousands of wats (temples) throughout the country including two small wats on the east coast and on the north end of Koh Lanta. When visiting a wat, wear appropriate clothing...beach shorts and tank tops are not appropriate. Monks should not be touched by women. The 2-handed “wai” greeting is common in Thailand. You may return the greeting with a smile, eyes cast downward and a slight bow or you should simply smile and say thank you. It is best that you do not initiate a “wai” as there is a protocol as to who should “wai” first. Thais are not used to skimpy clothing and topless or nude sunbathing is frowned upon.
